Yeah! We got the Wii version for xmas mostly for our son since he's too young to know what he's doing and it was cheaper and we figured Nintendo stuff holds up better over time. So it's great to hear that we can finally download more songs, because that was the only drawback when we got it.
I may be wrong here, but this is the first time I've seen Sony make a conscious effort to price the digital downloads of new release PSP games lower than what they sell for in stores. BlazBlue sells for $29.
